GRAIN-BINDING HARVESTER.

IEPBCIPICATION forming part of Letters Patent No. 350,812, dated October 12, 1886. Application filed J anuary 20, 1886. Serial No. 189,209 (No model.)

To aZZ whom it may concern.-

Be it known that I, ORVILLE COOLEY, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented a new and useful Improvement in Grain-Binders, of which the following is a specification.

My invention relates to improvements in grain-binding harvesters wherein the grain is bound through the instrumentalities found in what is known in the market as the Appleby Binder, and the object of my improvement is to provide an arrangement whereby the usual locking-lever shall be securely fastened 15 at the conclusion of the binding operation and prevent the knotter from repeating or making the second vibration incident to the rebound of the locking-lever. I attain this object by the mechanism illustrated in the accompany ing drawings, in which Figure 1 is a plan view of enough of the gear-train to illustrate the invention when the same is in a locked position, while the relative position of the moving parts previous to the consummation of the lock is shown in dotted lines; and Fig. 2 is a detached view ofthe supplemental locking-dog and the prime lockingarm.

Similar letters refer to similar parts in both views.

A is an intermittingly -revolving pinion mounted upon the continuously revolving shaft d, which also operates the packers. (Not shown.)

A is a gear-wheel meshing into pinion A, and is driven by the same.

A is an intermediate gear-wheel driven by A, and meshing into and driving the large gear-wheel A".

ais a wrist-pin projecting from the face of wheel A near the periphery of the same.

G is the connecting-rod uniting wheel A ,by means of wrist-pin a, with the crank-arm B, mounted upon shaft B, which also carries the twine-needle. (Not shown.)

C is a locking arm or lever pivotally connected with shaft B, and vibrating on the same.

O is an angle-arm rising upwardly from the heel or pivotal end of lever O, and forming a part of the said lever.

d is a rearwardly-curved rod secured to lever B, and passing up through the flange d upon lever O, and having coiled about it spring (2", and carrying the nut d. This spring at its lower end rests upon flange (1, while the upper end abuts against the nut (P, and is for the purpose of keeping the lever 0 down to its work, and also for adjusting and retaining the 1 same in vertical line with the striking end of the spring-dog F.

F is the clutch-head, which engages with the heel end of the dog F when the parts are unlocked, and by means of which the gear-train is set in motion and the gavel bound. This head F is permanently secured to the shaft 6, and at all times revolves with it. The said shaft also carries the packing-fingers, which are operated in the usual and well-known manner, but are not herein shown.

So far,with the exception of the angle-arm O, the parts enumerated are common in the Appleby machine. Myimprovement is found in the additional feature ofthe supplemental lockdog G. (Clearly shown in Fig.2.) This dog is centrally pivoted on the stud 9, upon which 7 5 the intermediate gear-wheel turns, and is provided with a tail-piece, g. This tail-piece rests upon and is guided by the arm 0, which in the throw of the arm causes the upper end of the supplemental locking-dog (of which the tail-piece forms a part) toimpinge against the under side of the wrist-pin a at a time slightly before the locking-arm Oreaches its lowest position and comes in contact with the springdog F, whereby the gear-wheels are held,and 8 5 until they are put in operation by the pressure of the inflowing grain.

It will be seen that while the supplementary lock is in coacting attitude with the arm and pin it supplies a rigid brace-connection be- 0 tween the parts and will not permit the arm to rise until the connection is severed by the onward movement of the pin in the revolution of the wheel upon which the pin is placed. This brace-connection is broken slightly pre- 5 vious to the consummation of the permanent look, but not until after the time for the rebounding of the arm, which is just before the lock is perfected.

In practical operation the grain is automatic- IOQ ally packed in thebinding-receptacle, and when a sufficient quantity is gathered therein to work the tripping device the locking-lever O is (by the necessary mechanism) raised, which 5 disengages it from the spring-dog F, and by this means the gear-Wheels are set in motion, and with them the entire binding machinery,

so that by the time the wheel A has made one entire revolution the gavel has been bound and I0 the sheaf discharged from the machine. By

this one revolution of the large Wheel the locking-lever O (by the connecting-rod) is made to rock backward and return again, so as to lock the driving mechanism until a succeeding gavel :5 shall be formed, when the operation is repeated. When the lever G is being brought forward and into position for placing the binding parts in a state 'of rest by the engagement of the arm with the spring-dog, the movement 20 is quite rapid, and as the dog during this descent is speedily revolving the concussion is so great thatin striking the-lever Git will often (Without the additional preventive found in the supplemental locking-dog) cause the le- 2 5 ver to rebound, thereby inducing the binding mechanism to repeat its operation before a sufficient quantity of the inflowing grain has,

accumulated for producing the ordinary-sized sheaf, and as a consequence the grain is scattered upon the ground in an unbound condition; or, if by chance the knot should be tied, the cord will only encircle a small quantity of grain, and as aoonsequenceadi minutive sheaf is formed.- Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1; In combination with the knotter-driving mechanism of a selfbinding harvester, the supplemental locking-dog G, the lateral1y-projecting pivotal stud g, the pin a, and arm 0, all arranged and operating substantially as described, and for the purpose herein set forth.

2. The combination, in a self-binding harvester, of the supplemental locking-dog G, the 45 tail-piece g, the pivot-stud g, pin cg, arm 0, and lockingrlever 0, all arranged and operating substantially as described, and for the purpose herein set forth.

ORVILLE COOLEY.
